Continuity in Rigid Viscoplastic Flow
… evolution equation for the rotation field in rigid viscoplasticity. The continuity condition provides a theoretical basis for assumptions of co-rotation models of crystal plasticity.

Large deformation of rigid-viscoplastic cantilevers subjected to impulsive loading
… is considered. The material is treated as rigid-viscoplastic; in this idealisation elastic effects are ignored, and the dependence of the yield stress on the rate of strain is taken into account. The problem is first analysed as one of impulsive loading, using the concepts of the mode …

The analysis of rigid-viscoplastic plane structures subjected to large impulsive loading
… is ignored, and the material is considered as rigidviscoplastic in order to take rate effects into account. Computational advantage is obtained by modelling this behaviour by a homogeneous viscous constitutive relation, as the rigid phase is absent. As opposed to the standard displacement …

Large deformations of thin plates subjected to impulsive loading
… has been obtained relatively simply using rigid-plastic or rigid-viscoplastic material idealisations. It is essential, however, that the predictions of these idealised theories should be checked against experimental results, and over the past twenty years several experimental studies have …

Non-Linear Finite Element Method Simulation and Modeling of the Cold and Hot Rolling Processes
… steel in hot rolling can be modeled using the rigid-viscoplastic (flow Levy-Mises) formulation, with a von Mises yield surface, and Shida's material model for high temperature steel where the flow stress is a function of the strain, strain rate, and the temperature. Other important …
